3) Choice C is absurd because either you're a Physicist who enjoys an occupation such as this, or you're just plain crazy.
4) Choice D is preposterous because either you're a Meteorologist, or a Geoscientist. Both of which have nothing to do with chemistry.
The Lithosphere ("rock sphere") is the ground you are standing on and the whole inside of Earth.
The Hydrosphere ("water sphere") includes all of the rivers, lakes and oceans of Earth.
The Cryosphere ("icy cold sphere") is the frozen part of Earth: the glaciers, icebergs at sea, and the huge icecaps in Greenland and Antarctica.
The Biosphere ("Life sphere") includes all living things: the trees in the park, the birds in the air, the fly on your wall, the viruses that make you sick, your pets, and even you and all your friends!
The Atmosphere ("Air Sphere") is the envelope of air that surrounds the whole Earth.
